Abstract
An all-solid-state lithium secondary battery includes a positive electrode; a negative electrode; and a solid electrolyte arranged between the positive and negative electrodes, to conduct lithium ions. In the all-solid-state lithium secondary battery, a mixed layer is in close contact with a surface of the solid electrolyte adjacent to the positive electrode, the mixed layer containing the positive-electrode active material and (Li, M)(B, A)O(wherein in the formula, M and A each represent at least one or more elements selected from C, Al, Si, Ga, Ge, In, and Sn, α satisfies 0≤α<1, β represents the valence of M, γ represents the average valence of (Li, M), y satisfies 0≤y<1, z represents the average valence of (B, A) and x, α, β, γ, z, and γ satisfy the relational expression (x(1−α)+xα/β)γ+z=2δ) serving as a matrix.
